Detailed implementation manners

[0040] In order to make the technical problems, technical solutions and beneficial effects solved by the present application clearer and more understandable, the following further details the present application in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0041] Please refer to Figures 1 to 12 , this embodiment provides a steerable anti - collision cushion, including a transition plate 2 with both sides respectively connected to the highway guardrail 1, the transition plate 2 is connected with two anchoring columns 3 fixed to the ground, the side ends of the anchoring columns 3 are respectively connected with a first energy absorption plate 4, two support frames 5 are connected between the pairwise - opposite first energy absorption plates 4, the lower part of the support frame 5 is slidably connected with two guide rails 6 anchored to the ground, and a second energy absorption plate 7 is respectively connected between the support frame 5 and the anchoring column 3 and between any two support frames 5.

[0042] In this embodiment, multiple support frames 5 can slide along the guide rail 6. Specifically, when the anti-collision pad is impacted by a collision object such as a car, it can be guided along the direction of the guide rail 6 to reduce the risk of deviation and rollover. In addition, the cross-section of the guide rail 6 can be T-shaped, circular, rectangular, etc., and no limiting structure is provided at the end, so that the support frame 5 can move uniquely along a predetermined trajectory during a collision. When it breaks away from the track, it can also absorb energy through the deformation of the anchoring column 3; the first energy-absorbing plate 4, the second energy-absorbing plate 7, and the support frame 5 together constitute a structurally compact energy-absorbing structure, which can effectively absorb collision energy and reduce the damage of the impact force to the collision object and the surrounding environment. It should be particularly noted that the difference between this embodiment and the anti-collision pad in the prior art is that the main energy-absorbing structure is an energy-absorbing plate with excellent energy-absorbing effect. Therefore, there is no need to set other components inside the anti-collision pad, which not only takes into account the anti-collision performance but also makes the design of the anti-collision pad lightweight and greatly reduces the production cost.

[0043] Further, as a preferred implementation manner rather than a limitation of this solution, the first energy-absorbing plate 4 includes at least two wave-shaped first energy-absorbing unit plates 41 connected end to end. A plurality of energy-absorbing holes 42 for buffering during a collision are uniformly arranged along the plate length direction between any two wave crests of the first energy-absorbing unit plate 41. One side of the first energy-absorbing unit plate 41 is also provided with a first mounting hole 43 corresponding to the energy-absorbing hole 42 on the adjacent first energy-absorbing unit plate 41. The first mounting hole 43 and the energy-absorbing hole 42 on the adjacent first energy-absorbing plate 4 are connected to the support frame 5 through fasteners.

[0044] In this embodiment, the first energy-absorbing plate 4 is composed of two wave-shaped first energy-absorbing unit plates 41, which can be added according to the anti-collision design requirements to improve the anti-collision ability. The wave-shaped structure of the first energy-absorbing unit plate 41 can increase the flexibility and deformation ability of the plate body, so as to better absorb and disperse collision energy.

[0045] On the first energy-absorbing unit plate 41, a plurality of energy-absorbing holes 42 are uniformly arranged along the plate length direction between any two wave crests. Specifically, the best setting positions of these energy-absorbing holes 42 are at the wave troughs between two wave crests and are linearly arranged along the length direction of the energy-absorbing plate. Of course, in some other embodiments, they can also be arranged on the inclined surface between the wave crest and the wave trough of the first energy-absorbing plate 7.

[0046] To realize the connection between the first energy-absorbing plate 4 and the support frame 5, a first mounting hole 43 corresponding to the energy-absorbing hole 42 on the adjacent first energy-absorbing unit plate 41 is provided on one side of the first energy-absorbing unit plate 41. By passing fasteners such as bolts or rivets through the first mounting hole 43 and the energy-absorbing hole 42 on the adjacent first energy-absorbing plate 4, the first energy-absorbing plate 4 can be firmly connected to the support frame 5.

[0047] In a real collision scenario, when a colliding object such as a vehicle collides with the steerable anti-collision pad proposed in this embodiment, the first energy absorption plate 7 deforms along the direction of the guide rail 6, and the energy absorption holes 42 on the first energy absorption plate 7 will be pressed against the fasteners and subjected to shear force to deform them, thereby achieving the effect of energy absorption and buffering until the energy absorption holes 42 are torn. Another energy absorption hole 42 adjacent to the energy absorption hole 42 will continue to be stressed and deformed to absorb energy, reducing the adverse effects of the impact on the vehicle and personnel.

[0048] Further, as Figure 4 、 Figure 6 、 Figure 7 shown, the energy absorption hole 42 is a polygonal hole with each inner side tangent to the fastener. The tangency design of the polygonal energy absorption hole 42 and the fastener can enhance the connection stability between the fastener and the first energy absorption plate 4, reducing the risk of loosening or falling off during the impact. On the other hand, when the polygonal energy absorption hole 42 is subjected to an impact, its shape helps to concentrate the impact force, and it is more likely to generate stress concentration and thus undergo energy absorption deformation compared to an ordinary round hole, improving the energy absorption efficiency.

[0049] Specifically, as Figure 4 shown, the energy absorption hole 42 is preferably an equilateral triangle hole, and one of the edges of the equilateral triangle hole is oriented in the same direction as the length direction of the first energy absorption plate 4. When a collision occurs, the edge of the equilateral triangle hole can be pressed against the fastener and absorb energy under shear. The triangle has the characteristic of strong stability, but when encountering a collision, the edge of the triangular hole is more likely to generate stress concentration and thus be squeezed and deformed than other shapes. Utilizing this characteristic, the energy absorption hole 42 can have a good energy absorption and buffering effect. In some other embodiments, the energy absorption hole 42 can also be in the shape of a rhombus, rectangle, regular hexagon, etc.

[0050] Further, as Figure 5 shown, the energy absorption hole 42 is a curved hole with a continuous smooth curve and an inner side tangent to the fastener. In some other embodiments, the energy absorption hole 42 can also be in the shape of a round hole, oblong hole, elliptical hole, etc. with a continuous smooth curve. Different from the regular polygonal energy absorption hole, the anti-collision pad with a curved energy absorption hole has a higher stiffness and thus better durability. However, because the stress distribution it receives during the impact is relatively more uniform, its energy absorption and buffering effect is slightly worse than that of the anti-collision pad with a regular polygonal energy absorption hole.

[0051] Furthermore, as a preferred embodiment of the present scheme but not a limitation, a gasket 44 is provided between any two wave peaks of the first energy absorbing unit plate 41 to prevent the fastener from detaching when the energy absorbing hole 42 is deformed by collision. The fastener passes through the gasket 44, the energy absorbing hole 42, and the first mounting hole 43 on the adjacent first energy absorbing unit plate 41 from the outside to the inside in sequence and is then fixed to the support frame 5. The cross-sectional shape of the gasket 44 matches the waveform of the first energy absorbing unit plate 41.

[0052] In this embodiment, the gasket 44 is used to compress the first energy absorption unit plate 41, and at the same time prevent the bolts from coming out due to the increase in the hole diameter of the energy absorption hole 42 when the anti-collision pad is deformed by collision energy absorption, which is of great significance to maintaining the buffering energy absorption effect of the energy absorption hole 42.

[0053] Furthermore, as a preferred embodiment of the present solution but not a limitation, a raised surface 45 is provided on one end of the first energy absorbing unit plate 41 away from the first mounting hole 43 and close to the gasket 44 to avoid uneven energy absorption due to direct physical contact with the gasket 44 on the adjacent first energy absorbing unit plate 41 when collision deformation occurs.

[0054] Specifically, when a steerable anti-collision pad proposed in this embodiment is hit, the first energy absorbing unit plate 41 is squeezed and deformed and displaced backward. At this time, the edge of the deformed first energy absorbing unit plate 41 is likely to be pressed against the gasket 44 provided on the adjacent first energy absorbing unit plate 41, thereby resulting in uneven energy absorption. This situation can be effectively avoided by providing a raised surface 45.

[0055] Furthermore, the spacing between adjacent energy-absorbing holes 42 is 5-15 mm, preferably 10 mm. The setting of this spacing is based on a comprehensive consideration of the energy absorption efficiency and structural stability of the anti-collision pad. The anti-collision pad can achieve a more uniform energy absorption and buffering effect during the impact process, thereby improving the overall energy absorption efficiency. On the other hand, it facilitates the installation and maintenance of fasteners such as bolts or rivets, thereby ensuring a smooth installation process.

[0056] Further, as a preferred embodiment of the present invention but not limiting, the second energy absorbing plate 7 includes a curved plate 71. Figure 8 The surface of the arc plate 71 is provided with a plurality of stamped ribs 72 for improving the energy absorption effect. Both sides of the arc plate 71 are respectively provided with mounting edges 73 connected to the support frame 5. The mounting edges 73 are provided with second mounting holes 74 for fixing fasteners to the support frame 5.

[0057] In this embodiment, the second energy absorption plate 7 is mainly composed of an arc-shaped plate 71. This arc-shaped design helps to provide a better energy absorption and dispersion path when being impacted. The ribbed surface 72 formed by stamping on the surface of the arc-shaped plate 71 increases the local stiffness of the plate and also has a certain shrinkage performance, enabling it to achieve the energy absorption and buffering effect through local deformation when being impacted.

[0058] Further, as a preferred implementation manner rather than a limitation of this solution, the second energy absorption plate 7 includes a corrugated plate 75. Please refer to Figures 9 - 10 , the crests and troughs of the corrugated plate 75 are parallel to the support frame 5. Installation edges 73 connected to the support frame 5 are respectively provided on both sides of the corrugated plate 75, and second installation holes 74 for fixing the fasteners to the support frame 5 are provided on the installation edges 73.

[0059] Different from the second energy absorption plate 7 with the above-mentioned arc-shaped design, in this embodiment, by providing a corrugated plate 75 with crests and troughs parallel to the support frame 5, the corrugated plate 45 can work together with the support frame 5 to improve the overall energy absorption efficiency. Specifically, when the anti-collision pad is impacted, the corrugated plate 75 generates a compression displacement under the action of an external force, thereby achieving the effect of buffering and energy absorption.

[0060] Further, as a preferred implementation manner rather than a limitation of this solution, the support frame 5 includes a frame body 51. A socket part 52 matching the shape of the guide rail 6 is provided at the lower part of the frame body 51. Third installation holes 53 corresponding to the first installation holes 43 for installing the first energy absorption unit plate 41 are provided on both sides of the frame body 51, and fourth installation holes 54 corresponding to the second installation holes 74 for installing the first energy absorption plate 4 are provided at the upper part of the frame body 51.

[0061] In this embodiment, the socket part 52 matches the shape of the guide rail 6, enabling the support frame 5 to be stably connected to the guide rail 6, improving the stability of the overall structure of the anti-collision pad. At the same time, when being impacted, it can be guided along the length direction of the guide rail 6, reducing the risk of a collision object such as a vehicle rolling over or deviating.

[0062] Further, as a preferred implementation manner rather than a limitation of this solution, one of the multiple support frames 5 is disposed at an end of the first energy absorption plate 4 away from the anchoring column 3, and a front protection plate 8 is covered on its side end face. Flanking plates 81 that cover the ends of the two first energy absorption plates 4 are bent and extended from both side ends of the front protection plate 8. A plurality of mounting portions 82 fixedly connected to the first energy absorption plate 4 are provided on the flanking plates 81. When a collision occurs, the front protection plate 8 prevents the first energy absorption plate 4 from directly physically contacting the collision body; a reflective sign 83 for improving visibility under night and bad weather conditions is further provided on the surface of the front protection plate 8, which helps improve the visibility of the anti-collision pad and reduce the collision risk at night or in low visibility conditions.

[0063] In this embodiment, for the support frame 5 located at an end away from the anchoring column 3, a front protection plate 8 is covered on its side end face. This protection plate provides an additional protective layer for the anti-collision pad to resist direct impact. At the same time, flanking plates 81 are bent and extended from both side ends of the front protection plate 8, and these flanking plates cover the ends of the first energy absorption plate 4 to avoid direct physical contact with the collision object. For example, in an actual scenario, it can effectively prevent a car from being penetrated by the first energy absorption plate 4 when colliding with the anti-collision pad.

[0064] Furthermore, as a preferred implementation manner rather than a limitation of this solution, the transition plate 2 includes a first connection portion 21 fixed to the anchoring column 3. The first connection portion 21 is connected to a transition portion 22 with an inclined angle for smoothly connecting to the highway guardrail 1. The transition portion 22 is connected to a second connection portion 23 fixed to the highway guardrail 1; a fifth mounting hole 24 corresponding to the energy absorption hole 42 and allowing a fastener to pass through and be fixed to the anchoring column 3 is provided on the side of the first connection portion 21. A sixth mounting hole 25 corresponding to the second mounting hole 74 and allowing a fastener to pass through and be fixed to the anchoring column 3 is further provided on the surface of the first connection portion 21 facing the second energy absorption plate 7, so as to facilitate the fixation of the second energy absorption plate 7 and maintain the stability of the entire anti-collision pad when not being collided.

[0067] When the anti-collision pad is collided, the support frame can slide along the guide rail to achieve the guiding function, reducing the risk of offset and rollover of the collided object.

The first energy-absorbing plate is composed of multiple first energy-absorbing unit plates in a waveform, and each unit plate is provided with multiple energy-absorbing holes, which are connected to the support frame through fasteners. When a collision occurs, the energy-absorbing holes interact with the fasteners to achieve the energy absorption and buffering effects.

The preferred shape of the energy-absorbing hole is an equilateral triangle hole, and one of the edges is oriented in the same direction as the length direction of the first energy-absorbing plate to enhance the energy absorption effect.

[0069] Gaskets and raised surfaces are provided on the first energy-absorbing unit plates to prevent the fasteners from detaching when the energy-absorbing holes are deformed during a collision and to avoid direct contact between adjacent first energy-absorbing unit plates, resulting in uneven energy absorption.

[0070] The second energy-absorbing plate includes an arc-shaped plate or a waveform plate, and the surface is provided with multiple rib surfaces formed by stamping to improve the energy absorption effect. Installation edges are provided on both sides of the arc-shaped plate or the waveform plate, which are connected to the support frame through fasteners.

[0071] The support frame includes a frame body, and a socket part matching the shape of the guide rail is provided at the lower part. Third installation holes for installing the first energy-absorbing unit plates are provided on both sides, and fourth installation holes for installing the second energy-absorbing plate are provided at the upper part.

[0072] A front protection plate is provided on the support frame at the end far from the anchoring column, and wing plates are bent and extended at both side ends to cover the ends of the first energy-absorbing plate and avoid direct contact with the collided object. Reflective markings are also provided on the surface of the front protection plate to improve visibility at night and in bad weather conditions.

[0073] The transition plate includes a first connection part fixed to the anchoring column, a transition part with an inclined angle, and a second connection part fixed to the highway guardrail. Fifth installation holes and sixth installation holes are provided on the side part of the first connection part and on the surface facing the second energy-absorbing plate for cooperating with the fasteners to achieve the fixed connection with the anchoring column.

[0074] A kind of anti-collision pad with guiding function proposed by the utility model can achieve effective energy absorption and buffering when being collided, and at the same time has good guiding performance, reducing the risk of offset and rollover of the collided object and improving the anti-collision effect.

[0075] The above are the implementation manners provided in combination with specific contents, and it is not determined that the specific implementation of this application is only limited to these descriptions. Any structure similar to the method of this application, or several technical deductions or replacements made under the premise of the concept of this application, should be regarded as the protection scope of this application.
